An elusive chest coin in an african child: a pleural fibroma’s long, tortuous path to freedom

Fibrous tumour of the pleural is rare and controversial tumor. Most of the reported cases is adults and the elderly. This case presentation is a solitary fibrous tumour in a fifteen year old girl, which to the best of our knowledge is the youngest report, who was sent for a psychiatric evaluation due to persistent complaint of "movement" in her chest, later referred to a tuberculosis clinic because of a chest radiograph report of loculated pleural effusion likely secondary to tuberculosis. She eventually had a chest computerized tomography and subsequent resection of the lesion. Histology confirmed the computerized tomography diagnosis of solitary fibrous tumour and there was no recurrence five years after excision. This report highlights the difficulty often encountered in developing countries where clinicians solely rely on clinical acumen for diagnosis and treatment due to poor patients' financial status and scarcely available diagnostic resources.Pan African Medical Journal 2013; 14:1

Management of Adult Choledochal Cyst Coexisting with Gallbladder Carcinoma: A Case Report and Review of Literature

Choledochal cyst is a relatively rare condition. Even rarer is a choledochal cyst in association with a gallbladder carcinoma. This study reports a rare case of gallbladder carcinoma coexisting with a choledochal cyst in a Nigerian patient. Clinical records of the patient including preoperative evaluation, intraoperative findings, and postoperative care were reviewed. A 38-year-old woman presented with the recurrent right upper abdominal pain of 3 years duration associated with progressive weight loss, anorexia, recurrent vomiting, as well as, low-grade fever with chills and rigors. Physical examination revealed an anicteric woman with tenderness in the right hypochondrium and a positive Murphy's sign. A combination of abdominal ultrasound and computed tomography scan suggested a Type IV choledochal cyst and a distended gallbladder with thickened walls containing a heterogeneous hyperdense mass. Preoperative serum alkaline phosphatase was elevated while endoscopic retrograde cholangiopancreatography was inconclusive. At laparotomy, extrahepatic biliary dilatation and enlarged, the nodular gallbladder was found with a diffusely fibrotic pancreas. Intraoperative cholangiogram confirmed Type IV choledochal cyst. Excision of the common bile duct and radical cholecystectomy was performed, and a Roux-en-Y hepaticojejunostomy. Histopathology confirmed the diagnosis of gallbladder adenocarcinoma. She had adjuvant chemotherapy and is presently on follow-up. No evidence of recurrence after 5 years of follow-up. A high index of suspicion is required to detect a combination of these two rare entities. When detected, both conditions should be surgically addressed at the same sitting, and when combined with adjuvant chemotherapy, may increase the chances of achieving a cure.Keywords: Adult, choledochal cyst, gallbladder cancer, jaundice, surgery, Nigeri

Optic nerve sonography: A noninvasive means of detecting raised intracranial pressure in a resource-limited setting

Objective: The aim was to assess the use of optic nerve sonography (ONS) as a quick, noninvasive diagnostic test tool for detecting raised the intracranial pressure (ICP). Materials and Methods: A prospective blinded observational study was conducted at Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Nigeria. The study population consisted of 160 adult patients referred to the radiology department for cranial computed tomography (CT) scan. There were 80 subjects and 80 controls. Optic nerve sheath diameter (ONSD) was measured by a radiologist using a 7.5 Megahertz ultrasound probe while cranial CT was reviewed by other radiologists blinded to the ONSD. Results: Sixty-nine subjects (86.3%) had intracranial space occupying lesions (SOL) with cranial CT confirmed features of increased ICP, mean binocular ONSD of 5.7 ± 0.59 mm while 11 (13.7%) had intracranial SOL without any cranial CT evidence of increased ICP, mean binocular ONSD of 4.8 ± 0.39 mm. The difference of mean ONSD of the two groups was statistically significant (P = 0.0001). The controls had a mean binocular ONSD of 4.5 ± 0.22 mm and the difference in mean binocular ONSD for subjects with raised ICP and the controls were also statistically significant (P = 0.0001). A cut-off value of 5.2 mm (sensitivity 81.2% [95% confidence interval (CI): 69.9–89.6], specificity 100% [95% CI: 71.5–100]) was obtained from the receiver operator characteristics curve as the mean binocular ONSD that best predicts raised ICP confirmed by at least a sign on cranial CT. Conclusions: Optic nerve sonography can differentiate between normal and elevated ICP and may serve as a useful screening tool in resource-limited practice

Reference Ranges of Fetal Cerebral Lateral Ventricle Parameters by Ultrasonography Intervalos de referência para parâmetros do ventrículo lateral de cérebros fetais por ultrassonografia

Abstract Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-tochoroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined anterior horn measurement (CAHM) were taken. Methods This was a cross-sectional study involving 400 normal singleton pregnant subjects whose gestational ages were between 14 and 40 weeks. Transabdominal sonography was performed to obtain the values of the fetal cerebral lateral ventricle (FCLV) parameters. Data were reported as mean AE standard deviation (SD) for continuous variables. The degrees of correlation between FCLV parameters and the estimated gestational age (EGA) were obtained using Pearson's correlation. Regression equations were used to generate the reference limits for the FCLV measurements. Results The values of AW, V-C measurements and CAHM increased with advancing gestation. The mean values of the AW, V-C and CAHM from 14 to 40 weeks increased from 6.60 AE 0.94 mm to 9.75 AE 0.07 mm (R 2 ¼ 0.114), 0.80 AE 0.00 mm to 1.90 AE 0.14 mm (R 2 ¼ 0.266), and 6.95 AE 0.06 mm to 23.07 AE 4.02 mm (R 2 ¼ 0.692) respectively, while the mean VHR decreased from 61.20 AE 1.60% to 42.84 AE 2.91% (R 2 ¼ 0.706) over the same period. Conclusion The AW, V-C, and CAHM increase, while VHR decreases with advancing gestation. Resumo Objetivos O presente estudo objetiva avaliar as dimensões do ventrículo lateral de cérebros fetais por meio de ultrassonografia transabdominal.
